will the FIFO pointer increase after send data to FIFO by EPxFIFOBUF? | Cypress Semiconductor
will the FIFO pointer increase after send data to FIFO by EPxFIFOBUF?
hi, Sir/ Madam
now I want to use the GPIF to collect data from an ADC. every convertion will product 6 words of data. These data will be write into the FIFO(e.g. using the EP2). I know the FIFO pointer will increase after the data bus on "Activate".
but I have to give a time stamp before the 6 words be writed into the FIFO. I want to use EPxFIFOBUF to accomplish this goal.
however, I am afraid the GPIF will overlap the time stamp.
If I use the EPxFIFOBUF, like
EPxFIFOBUF = 14;
atfer this opration, will the FIFO pointer point to the EPxFIFOBUF, or the FIFO pointer won't have any different?
by the way, can I use the FIFO pointer directly in the 8051? Like what the GPIF do.
thanks a lot!
